Impossible to say without the codes.i dont want to dredge up old posts but i have no choice here, Ive had the vsa /abs light on for two months now. im loathed to take my car to honda or any other mechanic and find out what the problem is.
The light came on after a month of replacing the rear brake pads (june 2012), Yesterday i jut came off the motorway and i head a (Clink!!!) coming from the rear right caliper. on closer inspection i see the pad worn to nothing.
With relic saying the sensor in the rear right hub controling abs control could this be linked to the caliper binding and the sensor picking up that fault, or heat damage to the sensor from the binding caliper. Some honda Boffins required here.
